Specific embodiment

In order to which the purpose, technical solution and beneficial effect of the application is more clearly understood, with reference to the accompanying drawings and embodiments, the application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, it is not used to limit the application.

The embodiment of the present application is suitable for LTE, and other networks that can support carrier aggregation technology, for example support dual carrier technology (Dual Carrier) Universal Mobile Communication System land radio access web (Universal Mobile Telecommunications Syste Terrestrial Radio Access Network, abbreviation UTRAN), support downlink dual carrier technology (Downlink Dual Carrier) enhanced data rates global system for mobile communications evolution technology wireless access network (Global System for Mobile Communication Enhanc Ed Data Rate for GSM Evolution Radio Access Network, abbreviation GERAN) etc..

In the embodiment of the present application, term " user equipment " includes but is not limited to the user equipment that can be worked in wireless environments of movement station, fixation or moving user unit, pager, cellular phone, personal digital assistant (Personal Digital Assistant, abbreviation PDA), computer or any other type.Term " base station " includes but is not limited to the interface equipment that can be worked in wireless environments of base station, node, station control, access point (Access Point, abbreviation AP) or any other type.Term " member carrier " specifically refers to the carrier wave for being able to carry out CA, can be the carrier wave in authorized spectrum band, or the carrier wave in unauthorized frequency range.

The embodiment of the present application can be used for various CA scenes, the interior CA that is not limited to stand, stand between CA, heterogeneous network CA etc..

In the prior art, cross-carrier scheduling (cross-carrier scheduling) is allowed in CA, i.e., dispatches PDSCH (the Physical Downlink of other serving cells by the PDCCH/ePDCCH in a cell Shared Channel, Physical Downlink Shared Channel) or PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel).As shown in Figure 1, for cross-carrier scheduling schematic diagram in the prior art.The resource block on CC2 and CC3 can be dispatched by the PDCCH of CC1.Since main carrier is identical with the TTI of secondary carrier, therefore when cross-carrier scheduling, pass through DCI (the Downlink Control Information carried in main carrier PDCCH/ePDCCH, Downlink Control Information) in CIF (Carrier indicator field, carrier wave instructions field) indicate carrier wave locating for the resource block being scheduled, so that it may TTI locating for the subframe where the determining resource block being scheduled --- because of TTI locating for resource block scheduled in secondary carrier necessarily with TTI locating for resource block scheduled in main carrier in section at the same time.If the corresponding TTI of main carrier is greater than the corresponding TTI of secondary carrier, a TTI in main carrier may correspond to multiple TTI in secondary carrier, and CIF can only indicate carrier wave locating for scheduled resource block, so as to cause user equipment after determining carrier wave locating for scheduled resource block according to CIF, TTI locating for the subframe where scheduled resource block can not be determined.As shown in Fig. 2, being a kind of cross-carrier scheduling schematic diagram provided by the embodiments of the present application.TTI in Fig. 2 in CC1 is equal to TTI, respectively TTI 1 and TTI 2 in 2 CC2.In Fig. 2, when dispatching the resource on CC2 by the PDCCH of CC1, the carrier wave where base station can only indicate scheduled resource block by CIF is CC2, and the subframe where not can indicate that scheduled resource block is located at TTI 1 or TTI 2 in CC2.

In the embodiment of the present application, the length of TTI and subframe in the same carrier wave be it is identical, i.e., the length of one subframe is exactly the length of a TTI.But TTI is that the concept of a scheduling level, base station and user equipment are transmitted by unit arrangement data of TTI；And subframe is the concept of a physical layer, physical layer arranges the processing behavior of base band and radio frequency as unit of subframe.In present LTE system, both is equivalent in time span.But in actual operation, do not impose the two concepts equivalent.For example in a TTI may include multiple subframes, at this moment, MAC layer arranges to transmit as unit of TTI, but physical layer is handled as unit of subframe.In this case, it in the embodiment of the present application, need to only indicate locating for the subframe where resource block to TTI.

To solve the above-mentioned problems, the embodiment of the present application provides a kind of cross-carrier dispatching method, is further explained below.

Based on foregoing description, as shown in figure 3, the embodiment of the present application provides a kind of cross-carrier dispatching method stream Journey schematic diagram, comprising:

Step 301, base station determines that TTI indicates information according to the resource block for dispatching user facility, and TTI instruction information is used to indicate the position that TTI locating for the subframe where the resource block is located in scheduled carrier wave.

In the embodiment of the present application, scheduling carrier wave can refer to for the carrier wave of the resource block in other carrier waves (such as secondary carrier) of dispatching user facility.Scheduled carrier wave can refer to the carrier wave that the resource block in carrier wave is dispatched by other carrier waves (such as main carrier), can be secondary carrier.

In step 301, base station is that the resource block of dispatching user facility can be ascending resource block, or downlink resource block.Meanwhile the scheduled carrier wave does not limit band limits, can be the carrier wave in unauthorized frequency range, the scheduled carrier wave can also be the carrier wave in authorized spectrum band.Here authorized spectrum band refer to country, area or tissue authorize when telecom operators provide that user equipment is mobile and the communication services such as linking Internet access net (such as above-mentioned base station) with used frequency range, such as various wireless access standard frequency ranges as used in LTE, UTRAN and GERAN etc. are communicated between user equipment.Unauthorized frequency range refers to the frequency range except above-mentioned authorized spectrum band, common are using frequency range used in WLAN, broadcast television signal and satellite communication of Wireless Fidelity (wireless fidelity, Wi-Fi) technology etc..

The embodiment of the present application can be adapted for situations such as scheduled corresponding TTI of carrier wave is less than the corresponding TTI of scheduling carrier wave, the scheduled corresponding TTI of carrier wave is equal to the corresponding TTI of scheduling carrier wave, the scheduled corresponding TTI of carrier wave is greater than scheduling carrier wave corresponding TTI.It will be illustrated so that the scheduled corresponding TTI of carrier wave is less than the corresponding TTI of scheduling carrier wave as an example below, other situations can be with reference to the description in the embodiment of the present application, and details are not described herein.

Base station can determine that TTI indicates information after having determined as the resource block of dispatching user facility, indicate the position being located in scheduled carrier wave for TTI locating for the subframe where the resource block of dispatching user facility.

In the embodiment of the present application, TTI that base station is determined instruction information can serve to indicate that TTI locating for the subframe where the resource block is located at the position in N number of TTI, N number of TTI can be the TTI, the main TTI for being in the same period in the scheduled carrier wave with the main TTI in the scheduling carrier wave With TTI locating for the subframe of the subframe simultaneous transmission where the resource block, N to be positive integer in the scheduling carrier wave.

Optionally, TTI indicates that information can be K TTI mark, and each TTI mark indicates the position that a TTI is located in N number of TTI, and K is positive integer.Wherein, what the corresponding relationship that TTI mark and TTI are located at the position in N number of TTI can make an appointment between base station and user equipment.Wherein, K is less than or equal to N.

TTI mark and the TTI corresponding relationship for being located at the position in N number of TTI can be sent to user equipment by RRC (Radio Resource Control, wireless heterogeneous networks) signaling by base station.Certainly, TTI mark and the TTI corresponding relationship for being located at the position in N number of TTI can also be sent to user equipment, the embodiment of the present application does not limit this while sending TTI instruction information by base station.

For example, in conjunction with Fig. 2, N is 2 at this time.Base station is that the resource block of dispatching user facility is located in the TTI 1 of CC2.The TTI mark of TTI 1 in CC2 can be that the TTI mark of the TTI 2 in 0, CC2 can be 1.At this point, TTI instruction information can be 0.User equipment can determine that resource block is located in the TTI 1 of CC2 after determining that the TTI received indicates that information is 0.Certainly, the TTI mark of TTI 1 or the TTI mark of 1, TTI 2 or 0, TTI mark are only required to each TTI of unique identification, and the embodiment of the present application does not limit the specific value that TTI is identified.

Further, in the embodiment of the present application, for a specific user equipment, base station can guarantee that the data of the user equipment are only possible to send in the part TTI in N number of TTI, so only needing to be directed toward the available TTI of the user equipment for the TTI mark in the TTI instruction information of the user equipment.For example, the TTI of 10 0.1ms in the corresponding scheduled carrier wave of the TTI of a 1ms of scheduling carrier wave.According to the time sequencing of TTI, the TTI mark of the TTI of this 10 0.1ms can be 0 to 9 respectively, but for some user equipment, the data of the user equipment, which are only possible to appear in TTI and are identified as 0 and TTI, to be identified as in 4 TTI, so being directed to the user equipment, TTI, which is identified as 0, can indicate that the 1st TTI, TTI are identified as 1 and can indicate that the 5th TTI, i.e., mentioned-above TTI are identified as 4 TTI.

TTI indicates that information can also be the resource block number of the resource block, to indicate the position of the TTI where subframe locating for the resource block.It wherein, include multiple resource blocks in a subframe, the resource block number numbered as each resource block that can will be arranged for each resource block.For example, in conjunction with Fig. 2, The resource block number for the resource block that TTI 1 includes in CC2 is that the resource block number for the resource block that 0 to 49, TTI 2 includes is 50 to 99.TTI indicates that information can be the resource block number of the resource block, when the resource block that resource block number is 21 to 40 in the main TTI 1 of PDCCH that base station passes through CC1, when user equipment indicates the resource block that information determines that base station is 21 to 40 for the resource block number of the resource block of its scheduling according to TTI, so that it may determine that the resource block is located in the TTI 1 of CC2.Accordingly, when the resource block that resource block number is 79 to 99 in the main TTI 2 of PDCCH that base station passes through CC1, when user equipment indicates the resource block that information determines that base station is 79 to 99 for the resource block number of the resource block of its scheduling according to TTI, so that it may determine that the resource block is located in the TTI 2 of CC2.This identification method substantially implicitly illustrates the TTI where scheduled data.

In the embodiment of the present application, TTI indicates that information can also be CIF.When TTI instruction information is CIF, base station is that the position that TTI locating for subframe where the resource block of dispatching user facility is located in scheduled carrier wave is predeterminated position.Predeterminated position can be sent to user equipment by RRC signaling by base station.Certainly, predeterminated position can also be sent to user equipment, the embodiment of the present application does not limit this while sending TTI instruction information by base station.

For example, in conjunction with Fig. 2, predeterminated position is first TTI corresponding with the main TTI in scheduling carrier wave, i.e. TTI 1 in scheduled carrier wave.When user equipment receives CIF, it can determine that base station is located at first TTI corresponding with the main TTI in scheduling carrier wave for TTI locating for the subframe where the resource block of dispatching user facility.It is of course also possible to which predeterminated position is also possible to TTI 2.

It can also be the resource block in dispatching user facility up-link carrier by descending carrier it should be noted that can be the resource block in dispatching user facility descending carrier by descending carrier in the embodiment of the present application.

For example, as shown in figure 4, being a kind of cross-carrier scheduling schematic diagram provided in the embodiment of the present application.In Fig. 4, the TTI in CC1 is equal to the TTI in 2 CC2.CC1 is descending carrier, and CC2 is up-link carrier.In Fig. 4, when dispatching the resource block on CC2 by the PDCCH/ePDCCH of CC1, base station can indicate that TTI locating for the subframe where the resource block that information instruction is dispatched on CC2 is located at the position in CC2 by TTI.In Fig. 4, if the resource block of scheduling is located at the n+8 subframe in CC2, TTI instruction information just uses 0 instruction, if the resource block of scheduling is located at the n+9 subframe in CC2, TTI Instruction information just uses 1 instruction.It should be noted that assuming that scheduling information and the scheduled resource block in CC 2 of CC 1 differ the corresponding TTI of 4 CC 1 in time in Fig. 4, in actual motion, this time difference can be other arbitrary values, herein without limitation.

When base station is by the resource block that descending carrier is in dispatching user facility up-link carrier, base station can send upstream data or all possible uplink signaling with scheduling user's set in the resource block, such as, base station scheduling user's set sends aperiodicity CSI (Channel State Information in the resource block, channel state information), aperiodicity SRS (Sounding Reference Signal, Sounding Reference Signal) etc..

Further, base station is while scheduling user's set sends upstream data or uplink signaling in the resource block, symbol can also be sent to user equipment and indicates information, and the symbol that instruction carries the uplink signaling or upstream data is located at the position in the subframe where the resource block.Symbol indicates that information can be the information such as the station location marker of symbol.Term " symbol " can refer to OFDM symbol when being described by taking LTE system as an example in the embodiment of the present application.

Step 302, the base station sends the TTI to the user equipment by scheduling carrier wave and indicates information.

In step 302, scheduling carrier wave can be the carrier wave in unauthorized frequency range, alternatively, scheduling carrier wave can also be the carrier wave in authorized spectrum band.It should be noted simultaneously that scheduling carrier wave can refer to that main carrier, scheduled carrier wave can refer to secondary carrier in the embodiment of the present application.

Base station can send the TTI to user equipment by the DCI carried in the PDCCH/ePDCCH of scheduling carrier wave and indicate information.

Step 303, user equipment, which is received, indicates information by the TTI that scheduling carrier wave is sent.

Step 304, the user equipment indicates that TTI locating for the subframe where the resource block that information determines that base station is dispatched is located at the position in scheduled carrier wave according to the TTI.

In step 304, user equipment can be with the PDCCH/ePDCCH of blind examination scheduling carrier wave, and obtains CIF in the DCI of PDCCH/ePDCCH carrying, so that it is determined that scheduled carrier wave.User equipment indicates that the resource block that information determines that base station is dispatching user facility is located at the position being scheduled in carrier wave after determining scheduled carrier wave, according to TTI, so as to transmit data according to the resource block or receive data.

When TTI indicates that information is K TTI mark, user equipment can identify K TTI locating for the subframe where determining the resource block in N number of TTI according to the K TTI, N number of TTI is the TTI for being in the same period in the scheduled carrier wave with the main TTI in the scheduling carrier wave, and the main TTI is TTI locating for the subframe in the scheduling carrier wave with the subframe simultaneous transmission where the resource block.

It should be noted that two subframe simultaneous transmissions can refer to has intersection in two corresponding TTI of subframe in time.For example, in conjunction with Fig. 2, the corresponding subframe of TTI 1 subframe corresponding with the TTI 1 in CC2 in CC1 and the corresponding subframe of TTI 2 in CC2 are the subframe of simultaneous transmission.

For example, in conjunction with Fig. 2, it can be 1 that the TTI mark of the TTI 1 in CC2, which can be that the TTI of the TTI2 in 0, CC2 identifies,.User equipment can determine that resource block is located in the TTI 1 of CC2 after determining that the TTI received indicates that information is 0；User equipment can determine that resource block is located in the TTI 2 of CC2 after determining that the TTI received indicates that information is 1；User equipment can determine that resource block is located in the TTI2 of TTI 1 and CC2 of CC2 after determining that the TTI received indicates that information is 01.

Further, in the embodiment of the present application, for a specific user equipment, base station can guarantee that the data of the user equipment are only possible to send in the part TTI in N number of TTI, so only needing to be directed toward the available TTI of the user equipment for the TTI mark in the TTI instruction information of the user equipment.For example, the TTI of 10 0.1ms in the corresponding scheduled carrier wave of the TTI of a 1ms of scheduling carrier wave.The data of user equipment are only possible to appear in the 1st TTI and the 5th TTI.TTI, which is identified as 0, can indicate that the 1st TTI, TTI are identified as 1 and can indicate the 5th TTI.User equipment can determine that resource block is located in the TTI 1 of CC2 after determining that the TTI received indicates that information is 0 at this time；User equipment can determine that resource block is located in the 5th TTI of CC2 after determining that the TTI received indicates that information is 1.

When TTI indicates that information is the resource block number of resource block, user equipment resource block can be determined according to the resource block number received locating for TTI where subframe position.

For example, in conjunction with Fig. 2, the resource block number for the resource block that TTI 1 includes in CC2 is that the resource block number for the resource block that 0 to 49, TTI 2 includes is 50 to 99.When user equipment indicates the resource block that information determines that base station is 21 to 40 for the resource block number of the resource block of its scheduling according to TTI, so that it may determine The resource block is located in the TTI 1 of CC2.When user equipment indicates the resource block that information determines that base station is 79 to 99 for the resource block number of the resource block of its scheduling according to TTI, so that it may determine that the resource block is located in the TTI 2 of CC2.

When TTI indicates that information is CIF, user equipment can determine that TTI locating for the subframe where the resource block of base station scheduling is located at the position in scheduled carrier wave according to predeterminated position.

In the embodiment of the present application, user equipment can send uplink signaling or upstream data by the resource block.For example, user equipment can send the uplinks signalings such as aperiodicity CSI, aperiodicity SRS in the resource block.

Further, the symbol instruction information that user equipment can also be sent according to base station determines the position in the subframe where the symbol for carrying the uplink signaling or upstream data be located at the resource block.

For example, as shown in figure 5, being a kind of cross-carrier scheduling schematic diagram provided by the embodiments of the present application.In Fig. 5, subframe of the base station where indicating that information indicates resource block to user equipment by TTI is n+8 and n+9, meanwhile also indicating that information is located in the last symbol of subframe n+8 and the penultimate symbol of subframe n+9 to the symbol that user equipment instruction carries the uplink signaling or upstream data by symbol.

Further, in the embodiment of the present application, when resource block is ascending resource block and scheduled carrier wave is the carrier wave in unauthorized frequency range, user equipment it may also be desirable to according to LBT (listen before talk, Listen Before Talk) determine whether the resource block can be used, and when determining that the resource block can be used, uplink signaling or upstream data are sent by the resource block.

It for example, is the descending carrier in authorized spectrum band in conjunction with Fig. 5, CC1, CC2 is the up-link carrier in unauthorized frequency range.Subframe of the base station where indicating that information indicates resource block 1 to user equipment by TTI is n+8, the subframe where resource block 2 is n+9.If user equipment determines that resource block 1 can be used, resource block 2 can be used according to LBT, upstream data or uplink signaling can be sent in resource block 1 and resource block 2；If user equipment determines that resource block 1 is unavailable, resource block 2 can be used according to LBT, Upstream data or uplink signaling can be then sent in resource block 2；If user equipment determines that resource block 1 is unavailable, resource block 2 is unavailable according to LBT, upstream data or uplink signaling are sent not in resource block 1 and resource block 2.It is worth noting that, it is herein assumed that the chance that scheduled resource block only once occurs in scheduled carrier wave, in fact, base station can be pre-configured with a window, scheduled resource block can occur repeatedly in the window.User equipment can be LBT in chronological order, if it is successful, just sending upstream data or uplink signaling using scheduled resource block, if unsuccessful, just the next time scheduled resource block location in window again attempts to LBT before occurring, until LBT success, or until window terminates.

In LTE, the reliability of system is improved by using HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat-request) technology, reduces the error rate of grouping transmission.Following behavior example, user equipment decodes PDSCH (Physical Downlink Shared Channel in the specified corresponding soft buffer area of HARQ process according to the downlink resource distribution information on PDCCH/ePDCCH, Physical Downlink Shared Channel) in data, and ascending HARQ confirmation message is generated according to decoding result, feedback information is in PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) or PUSCH on be sent to base station, wherein, HARQ confirmation message can be ACK (Acknowledge, confirm response)/NACK (Negative Acknowledge, negative Response).Base station determines that carrying out HARQ retransmits or send new data according to the HARQ confirmation message received.

In carrier aggregation technology, when carrying out HARQ and CSI feedback, the HARQ confirmation message and CSI of multiple carrier waves can be fed back on a carrier wave, but since the TTI of carrier wave is identical, and intercarrier is fully synchronized, so mapping relations are one-to-one in time-domain resource.If carrier wave polymerize, main carrier is different from the TTI of secondary carrier, then may result in mapping relations in time-domain resource and no longer correspond.For example, as shown in fig. 6, being a kind of cross-carrier scheduling schematic diagram provided in an embodiment of the present invention.In Fig. 6, main carrier CC1, secondary carrier CC2.Base station is located in the subframe n and subframe n+1 of CC2 by the resource block that main carrier is dispatching user facility, according to the regulation of HARQ feedback window, user equipment needs to fed back through the reception state for the downlink data that the resource block in subframe n and subframe n+1 receives simultaneously in the subframe m+2 of CC1.According to existing feedback method, it is the feedback for the downlink data of subframe n, or the feedback of the downlink data for subframe n+1 that the feedback received, which cannot be distinguished, in base station.

To solve the above-mentioned problems, the embodiment of the present application provides a kind of feedback method, is further explained below.

Based on foregoing description, as shown in fig. 7, the embodiment of the present application provides a kind of feedback method flow diagram, comprising:

Step 701, user equipment receives N number of downlink data on N number of downlink subframe, and N is positive integer.

Step 702, the user equipment determines the target carrier for feeding back the response message of N number of downlink data, and sends the response message to base station by the target carrier.

In step 701, N number of downlink subframe can be N number of downlink subframe in secondary carrier.

In step 702, user equipment can generate response message according to the reception state of N number of downlink data, wherein reception state can be to be properly received or be not properly received after receiving N number of downlink data.

In the embodiment of the present application, the response message that user equipment generates may include N number of HARQ confirmation message and N number of subframe position instruction information.Each HARQ confirmation message and a subframe position instruction information are corresponding.For any one HARQ confirmation message in N number of HARQ confirmation message, the HARQ confirmation message is used to indicate the reception state of the downlink data carried in downlink subframe indicated by subframe position instruction information corresponding with the HARQ confirmation message.Each HARQ confirmation message can be ACK or NACK, can specifically be determined according to the reception state of the corresponding downlink data of HARQ confirmation message.

In the embodiment of the present application, subframe position indicates that information can identify for downlink subframe, and downlink subframe mark indicates that the downlink subframe identifies the position that corresponding subframe is located in carrier wave locating for the subframe.

It for example, from subframe n to the downlink subframe of subframe n+9 mark can be 0 to 9 in CC2 in conjunction with Fig. 6.When the reception state of the downlink data carried in user equipment feedback subframe n+1, the downlink subframe mark of transmission can be 1.

Further, in the embodiment of the present application, for a specific user equipment, base station can guarantee that the data of the user equipment are only possible to send in the part subframe of carrier wave, so only needing to be directed toward the available subframe of the user equipment for the subframe mark in the subframe position instruction information of the user equipment.For example, the TTI of 1 1ms of main carrier corresponds to the TTI of 10 0.1ms in secondary carrier, i.e., main load The transmission time length of 1 subframe in wave is equal to the transmission time length of 10 subframes in secondary carrier.The data of user equipment are only possible to appear in the 1st subframe and the 5th subframe.At this point, TTI, which is identified as 0, can indicate the 1st subframe, TTI, which is identified as 1, can indicate the 5th subframe.

Further, the corresponding relationship that downlink subframe mark is located at the position in carrier wave with downlink subframe can be sent to the user equipment by RRC signaling for base station.It is of course also possible to be sent to user equipment while sending downlink data for base station.

Subframe position indicates that information can also be the resource block number of the resource block of bearing downlink data.For example, in conjunction with Fig. 6, the resource block number for the resource block that subframe n includes in CC2 is 0 to 49, and the resource block number for the resource block that subframe n+1 includes is 50 to 99.User equipment numbers on the resource block for being 21 to 40 in subframe n and receives downlink data.The subframe position instruction information that user equipment is determined at this time can be respectively the resource block number for receiving the resource block of downlink data.

Optionally, response message can also the user equipment the corresponding N number of HARQ confirmation message of the N number of downlink data be subjected to logic and operation obtain.At this point, response message is just ACK when only all N number of downlink datas are all properly received；When any one downlink data is not properly received in N number of downlink data, response message is NACK, and base station needs to transmit all N number of downlink datas again at this time.

By this method, it is possible to reduce the data flow of response message transmission, to reduce system loading.

For example, in conjunction with Fig. 6.In Fig. 6, user equipment has correctly received downlink data in subframe n, downlink data is had correctly received in subframe n+1, the response message then generated is ACK, base station determines that response message is ACK after receiving response message, it is determined that user equipment has correctly received downlink data in subframe n and subframe n+1.User equipment has correctly received downlink data in subframe n, downlink data is not properly received in subframe n+1, the response message then generated is NACK, and base station determines that response message is NACK after receiving response message, it is determined that user equipment is not properly received downlink data.User equipment is not properly received downlink data in subframe n, downlink data is had correctly received in subframe n+1, the response message then generated is NACK, base station determines that response message is NACK after receiving response message, then determine that user equipment is not properly received downlink data, user equipment is not properly received downlink data in subframe n, and downlink data is not properly received in subframe n+1, then the response message generated is NACK.Base station determines that response message is NACK after receiving response message, it is determined that user equipment is not properly received To downlink data.

In the embodiment of the present application, when user equipment determines the target carrier for sending the response message, main carrier can be determined as target carrier, secondary carrier can also be determined as target carrier.

Further, user equipment can determine the shortest member carrier of TTI from available member carrier, and carrier index in the shortest member carrier of the TTI is identified the smallest member carrier and is determined as being used to feed back the target carrier of the response message of N number of downlink data.

It should be noted that in the embodiment of the present application, the carrier wave for transmitting PUCCH is then determined as available member carrier if it is determined that do not transmit PUSCH by user equipment；If it is determined that transmission PUSCH, then be determined as available member carrier for the carrier wave for transmitting PUSCH.

Step 703, base station receives the response message that user equipment is sent by target carrier.

Step 704, the base station determines the reception state of N number of downlink data that the user equipment receives on N number of downlink subframe according to the response message, and N is positive integer.

In step 704, base station is determined according to the response message received retransmits or sends new downlink data.

Response message be include N number of HARQ confirmation message and N number of subframe position instruction information when, if the HARQ confirmation message that base station receives is NACK, the downlink data carried in downlink subframe indicated by the corresponding subframe position instruction information of the HARQ confirmation message is transmitted again.

Response message be the user equipment by by the corresponding N number of HARQ confirmation message of the N number of downlink data carry out that logic and operation obtains when, the base station then sends N number of downlink data to the user equipment again if it is determined that the response message is NACK.The base station if it is determined that the response message be ACK, then new downlink data can be sent to the user equipment.

All assume that scheduling carrier wave and scheduled carrier wave use the TTI of different length in above-mentioned example, works under the scene of cross-carrier scheduling.Actually, above-mentioned condition can also be extended, such as, the same cell, section is worked using the TTI of different length in different times, such as within the scope of period 0-T1, use the TTI of 1ms, send scheduling instruction, notice UE downlink data resource block location is within the T2-T3 period or the resource block location of notifying user equipment upstream data is within the T2-T3 period.Within the scope of period T2-T3, the TTI of 0.1ms is used.In this case, it also can be used in the embodiment of the present application The method provided indicates the TTI of which specific 0.1ms within the scope of T2-T3.

Based on same idea, a kind of carrier wave dispatching device is provided in the embodiment of the present invention, for executing above method process.

As shown in figure 8, being a kind of carrier wave dispatching device structural schematic diagram provided by the embodiments of the present application.

Referring to Fig. 8, which includes:

Determination unit 801, for determining that Transmission Time Interval TTI indicates information according to the resource block for being dispatching user facility, TTI instruction information is used to indicate the position that TTI locating for the subframe where the resource block is located in scheduled carrier wave；

Transmission unit 802 indicates information for sending the TTI to the user equipment by scheduling carrier wave.
